Osteopenia scores; anyone know what this means?

[Guest guest]

Could they make this any harder to understand?????

From records...

" ... the incidence of spine fracture per 1000 person years for a 64 year old

patient is:

+2SD +1SD mean -1SD -2SD

4 5 9 18 35 "

I am thinking the first row of letters is how they grade the likely hood of

fracture (?) but what is that second line of numbers?

Later in the notes...

" L1 - L4 Lumbar Spine 0.965 -0.7 -0.1 46.0% "

L Total Hip 0.877 -0.5 -0.1 46% "
